명칭 : 1.Full-endoscopic(FE) technique via Intra-laminal(IL) and Trans-foraminal(TF) approach
2. The conventional microsurgical operations(방법: performed with paramedian or lateral access in known standardized technique using a microscope)
FE중 IL의 방법 : A dilator is inserted bluntly to the lateral edge of the IL window and an operation sheath with beveled opening directed toward the Ligamentum flavum.
FE 중 TF의 방법 : performed with access as lateral as possible. An atraumatic spinal cannula is inserted via the 6 mm skin incision.
After insertion of a lead wire, the cannulated dilator is pushed in. Then a surgical sheath with beveled opening is placed.
Thereafter, decompression is performed while maintaining visual control and constant irrigation.

87명은 microsurgerym, 91명은 full-endoscopic surgery(38명은 transforaminal, 53명은 intralaminal수술)3. 수술성과의 판정 방법(판정에 사용한 도구, 평가 점수)
2년후 146명이 leg pain 사라짐(MI 69명, FE 77명), 25명은 이따금씩의 pain을 가짐(MI=13, FE=12), 7명은 수술후 개선을 못느낌(MI=5, FE=2)VAS leg의 평균 (MI = 수술전 71에서 2년후 9로 떨어짐, FE= 수술전 75에서 8로 떨어짐)
